How does aws cloudtrail work with aws lambda?


Asked by Avayah Clay on Nov 29, 2021 FAQ



AWS Lambda is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service in AWS Lambda. CloudTrail captures API calls for AWS Lambda as events. The calls captured include calls from the AWS Lambda console and code calls to the AWS Lambda API operations.
Just so,
A trail enables CloudTrail to deliver log files of events to an Amazon S3 bucket. You can take advantage of Amazon S3's bucket notification feature and direct Amazon S3 to publish object-created events to AWS Lambda.
Next, CloudTrail is enabled on your AWS account when you create the account. When supported event activity occurs in AWS Lambda, that activity is recorded in a CloudTrail event along with other AWS service events in Event history. You can view, search, and download recent events in your AWS account.
Likewise,
Note that we cannot trigger Lambda from CloudTrail. Instead, CloudTrail stores all the history in the form of logs in S3 bucket and we can trigger AWS Lambda from S3. Once any logs are to be processed, AWS Lambda will get triggered whenever any logs are added to S3 bucket.
In respect to this,
If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for AWS Lambda. If you don't configure a trail, you can still view the most recent events in the CloudTrail console in Event history.
